SMUT-MACHINE.

Specification of Letters Patent No. 4,944, dated January 26, 184?.-

To all whom t may concern.'

Be it known that I, JOSEPH HEYGAL, of the city of Baltimore and State`of Maryland, have invented a new and useful Improvement inSmut-Machines, and that the following is a full, clear, and exactdescription of the principle or character which distinguishes it fromall other things before known and of the manner of making, constructing,and using the same, reference being had to the accompanying drawings,

making part of this specification, in which-- Figure l isa sideelevation, and Fig. 2 a longitudinal vertical section.

The same letters indicate like parts in all the figures. A

The nature of my improvement consists in the manner in which I dischargethe smut and receive the blast and in the form and application of therubbers or runners.

The construction is as follo-ws: The frame is of a suitable form andstrength to sustain the working parts and is keyed throughout. At theupper part of this frame is stationed at one end a hopper (a) into whichthe grain to be cleaned is put; thence it descends down an inclinedspout (Z2) in which is placed a fluted roller (0); the bottom of thespout is movable and is pressed up against the roller (c) by a spring(CZ) below, tempered by a set screwV (6); this serves to flatten theVgarlic as it descends with the grain into the first cylinder Thiscylinder or case is composed of any suitable material, the sides may beof wood and the periphery covered with sheet iron punched or with castiron in staves; on the upper half of this cylinder are four more or lesstriangular projections from the face of the circle as clearly shown at(e, e) in the drawing; the sides are pierced with a row of holes (f),around and near the axle of the runner; and near the periphery there isanother row of holes (z.) all around. These holes are all covered withwire gauze, and when the machine is cylinder (A) in operation the air isdrawn in through the center holes (f) and is forced out, together withthe smut, through the outer ones Within thisr case a runner is placedturning on an axle from which axle a series of arms radiate, these arefiat and form wings; the ends of said arms terminate in segments of acylinder that nearly fits the case (see Fig. 2); they are faced withsheet iron punched or with cast iron ribbed; by revolving they cause theheavy grain to run thro-ugh below but carry around the light grain,garlic, and smut and beat them against the triangular projections (e, e)above named. As the smut is disengaged it is blown out through the holesin the sides as before named. The grain and bruised garlic then passdown through the inclined spout (Z) into a second cylinder constructedlike the rst in all particulars; in this the operation is finished ofcleaning olf the grain, and so bruising the garlic as to-ft it for beingblown out from the wheat when received onto an inclined screen (m) whichreceives a blast from a fan (B) situated below the first described Thescreen (m) has a motion endwise and the grain received thereon fallsdown under the fan spout at (o) the screenings pass through at (n), thetailings at (p) and the bruised garlic is blown out at top.

Having thus fully described my improvements what I claim as my inventionand desire to secure by Letters Patent is- Constructing the case of ahorizontal smut machine with two rows of holes in the sides thereof, inthe manner described, for Ventilating and discharging the smut, and incombination therewith the runner constructed as above set forth for thepurposes above specified.
